Cities: Skylines

Here's a thought that just came to me (may not be possible but if it is it would be insane) - So we can add waypoints to lines so the vehicles go a certain route without adding a station. One thing that always bothered me was that at terminal stations you always have to use one platform. But what if you had a siding, set a waypoint there and the vehicle stopped at one terminal platform, used the siding to reverse back into the other one and goes on its way. Its something I've always wanted. Thanks for coming to my TED talk
